STEAM-CYLINDER FOR CLOTH SPONGING AND FINISHING MACHINES.

Specification of Letters Patent.

Patented Jan. 3, 1911.

Application filed March 11, 1910. Serial No. 549,042.

To all whom it may concern.

Be it known that I, ROBERT \V. HULL, a citizen of the United States ofAmerica, and a resident of .Hingham, in the county of Plymouth and Stateof Massachusetts, have invented certain new and useful Improvements inSteam-Cylinders for Cloth Sponging and Finishing Machines, of which thefollowing is a specification.

This invention relates to sponging and finishing cylinders for machinesadapted to steam, shrink, and finish woolons, worsteds, and othercloths.

The object of the present invention is to provide a cylinder which willgive a uniform shrinkage and a firm permanent finish to any materialpassed over the surface thereof.

The object of the invention is primarily to dissipate thesteam enteringat one end of the cylinder so that the most of the moisture iseliminated from the steam before it passes into the main chamber of thecylinder and through the open-ended tubes extending into the interiorthereof through the outer wall.

The invention consists in certain novel features of construction andarrangement of parts which Will be readily understood by reference tothe description of the drawings and to the claims hereinafter given.

Of the drawings: Figure 1 represents a section through a cylinderembodying the features of the present invention, a portion of one endthereof being shown in elevation. Fig. 2 represents a transverse sectionthrough the same, the cutting plane being on line 22 on Fig. 1, and Fig.3 represents a transverse section of the same, the cutting plane beingon line 3-3 on Fig. 1.

Similar characters designate like parts throughout the drawings.

In the drawings, 10 represents suitable bearings forming a part of acloth finishing machine. Resting .in these bearings are the trunnions 11formed upon the cylinder heads 12. The cylinder heads 12 fit into theopposite ends of a cylinder 13. Extending through the wall of thiscylinder from its outer face are a plurality of open-ended tubes 14 theinner ends of which terminate at some distance from the inner wall ofsaid cylinder thereby preventing, in the rotation of the cylinder, anyWater which may accumulate therein from passing through said tubes tothe exterior operating face of the cylinder.

One of the trunnions 11 has an opening therethrough through whichextends an inlet pipe 15 and opposite the discharge outlet of said pipeand secured to the inner face of a cylinder head is a cylindrical box 16having near its edges a plurality of perforations 17 As the steam entersthis box from the pipe 15 it will impinge against the imperforateportion of said box opposite to the discharge outlet and be partiallydissipated finally passing therefrom through the openings 17 into acompartment 18 formed by the cone-shaped partition 19 having at itssmall end a chamber 20 from which a tubular member 21 extends toward thecenter of the box 16 and terminates a short distance therefrom in aflaring end 22, the flanges of said flaring end serving the purpose ofpreventing any water from passing through this tubular member into thechamber 20. From the chamber 20 extends a plurality of perforated pipes23 toward the opposite cylinder head.

A cock 24 communicates with the chamber 18 and a cock 25 communicateswith the main chamber of the cylinder 13. In the operation of theinvention two cylinders are usually used, the cloth to be finished beingwound upon one cylinder as it is rotated by means of a handle 20 or somesimilar rotating device and as the cloth is thus wound upon the cylinderit is thoroughly steamed by the steam passing through the plurality ofopen-ended tubes extending into the interior.

WVhen all of the cloth has been wound upon one cylinder it is reversedand wound upon a second cylinder, thereby giving a uniform shrinkage tothe entire piece of material and a firm permanent finish.

By means of the trap, consisting of the box 16, the tubular member 21.,partition 19, and chamber 20, all of the water is collected in thecompartment 18 and only dry steam is permitted to enter the main chamberof the cylinder and pass through the tubes 14' to the goods beingoperated upon. This prevents the goods from becoming Wet during theprocess of finishing. The only water that can possibly get into the mainchamber of the cylinder is that which is condensed from the steam and asthe tubes 14 extend some little distance inwardly from the wall of thecylinder, it is an impossibility for this Water of condensation to passinto the open inner ends of these tubes.

When the cloth has been rolled upon one of the cylinders, the rotationof the cylinder is stopped with the cooks :24; and 25 in their lowermostpositions as indicated in the variv ous figures and these cocks are thenopened and any water that may be contained either within the compartment18 or the main chamber of the cylinder is withdrawn and the cooks arethen again closed. Then the cloth is unrolled from the cylinder eitheronto another cylinder or is prepared for the market, as may be desired.

The devices for dissipating the steam as it enters one end of thecylinder and removing from the live steam all of the moisture before itis permitted to pass into the perforated pipes within the body of thecylinder form a great improvement in cylinders of this class, as greatlyimproved results are obtained thereby.

Having thus described my invention, I claim:

1. In a device of the class described, the combination with suitablebearings; of a revoluble cylinder having trunnions resting in saidbearings; a plurality of open-ended tubes extending through theperipheral wall of said cylinder into the interior thereof; acone-shaped partition at one end of said cylinder forming a separatecompartment; a plurality of perforated pipes secured to the inner end ofsaid partition and extending lengthwise of said cylinder; a steam inletpipe extending through one trunnion into said compartment; and a cockcommunicating with said compartment.
